Liquid crystal display and manufacturing method thereof

A liquid crystal display comprising:

• a gate line formed on an insulation substrate;
• a data line insulated from the gate line and crossing the gate line;
• a thin film transistor comprising a control terminal connected to the gate line and an input terminal connected to the data line;
• a pixel electrode having a first area and connected to an output terminal of the thin film transistor;
• a common electrode having a second area and receiving a common voltage;
• and
• a floating electrode including a first floating electrode of which a portion faces the pixel electrode and a second floating electrode of which a portion faces the common electrode.

A method of manufacturing a liquid crystal display comprising:

• forming a pixel electrode having a first area and a second floating electrode on an insulation substrate;
• forming a first sacrificial layer having a first thickness on the pixel electrode, and a second sacrificial layer having a second thickness on the second floating electrode;
• forming a first floating electrode connected to the second floating electrode on the first sacrificial layer, and a common electrode having a second area on the second sacrificial layer;
• forming a roof layer on the first floating electrode and the common electrode;
• forming a liquid crystal injection hole to expose a side surface of the first and the second sacrificial layer;
• forming a first microcavity and a second microcavity by removing the first sacrificial layer and the second sacrificial layer through the liquid crystal injection hole;
• and
• injecting liquid crystal molecules in the first microcavity and the second microcavity through the liquid crystal injection hole.
